MagyarLenovo IdeaPad 320s-14IKB (i5-7200U, 920MX, SSD, FHD) Laptop Review
With the IdeaPad 320s-14IKB, Lenovo delivers a 14-inch office notebook. The laptop comes with a Kaby Lake-based processor and a dedicated graphics card. Therefore, the notebook provides enough performance for office tasks. The device is no stranger to us. We have already reviewed a sibling model. The competitors of the device include the HP 14, the Acer Swift 3 SF314-52G and the HP ProBook 440 G4.
Because both IdeaPad models are identically built, we shall skip the sections that deal with the case, input devices and the speakers. You can find all the relevant information in the review of the sibling model.

Maintenance
The device can be both serviced and upgraded. However, Lenovo did not provide the 14-incher with a maintenance hatch. In order to get to the internals, you will have to remove the bottom cover. For this, you will have to undo all the screws on the underside of the device. Subsequently, the bottom cover can be removed with the help of a plastic putty knife or an offset spatula. This will require some finger work because the bottom cover is fastened very firmly and the small holding clamps can break easily. After that, you will have access to all of the hardware: SSD, fan, BIOS battery, M.2 slot, Wi-Fi module, battery. The RAM is protected by a cover.
Display
The IdeaPad is equipped with the same Full HD screen as the previously reviewed sibling model. What we have here is an IPS panel with great viewing angles and contrast, which offers a very low brightness. Two identically built panels never match one hundred percent.
Unfortunately, at 90% brightness and below, the display exhibits PWM flickering with a frequency of 357 Hz.
You can find further information about the display in our review of the sibling model.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 357 Hz | ≤ 90 % brightness setting |  |
The display backlight flickers at 357 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 357 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17853 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Performance
With the IdeaPad 320s-14IKB, Lenovo has a 14-inch notebook in its product line-up. It offers enough performance for all current applications. The dedicated graphics card allows users to play video games, albeit in a limited fashion. Our review device can be had for 700 Euros ($863). Other hardware configurations are also available. The prices start at 400 Euros ($493).
Processor
The IdeaPad comes equipped with a Kaby Lake-based dual-core Core i5-7200U processor. What we have here is a ULV model with a TDP of 15 watts, which is going to be able to meet the demands of most users. The CPU operates at 2.5 GHz. By means of Intel’s Turbo Boost Technology, the clock rate can be increased up to 3.1 GHz (for both cores). The Turbo Boost works both when the laptop is running on battery and when it is plugged in.
We check whether Intel’s Turbo Boost Technology can be used over an extended period of time by running the multi-core portion of the Cinebench benchmark for 30 minutes in a continuous loop. The results stay consistently on the same level. There are no drops in performance to report.

System Performance
The combination of a Core i5 processor and a solid-state drive makes for a very responsive system. The PCMark results show that the laptop offers more than enough performance for such usage scenarios as Internet browsing and office work. Limited video game play is possible thanks to the dedicated graphics adapter. An increase in performance through enabling dual-channel mode is impossible, because the notebook has only one RAM slot.

Storage Devices
A SATA-III SSD from Liteon serves as the system drive. What we have here is a 2.5-inch model with a storage capacity of 256 GB. Right out of the box, only 184 GB is available to the user. The rest of the storage space is occupied by the Recovery Partition and the Windows installation files. The transfer rates of the SSD are good.
Inside the device, there is an empty M.2-2280 slot that can be used with a corresponding SSD. Which raises the question: “Why did Lenovo not equip the device with an M.2 SSD in the first place?” Users who would like to go with a combination of an SSD and an HDD will have to get both drives on their own. Here, Lenovo should have thought more about their customers.

Graphics Card
The IdeaPad comes equipped with a GeForce 920MX from Nvidia. What we are dealing with here is an entry-level GPU. It supports DirectX 12 and operates at core clocks of up to 980 MHz. Unlike the GeForce 920M (Kepler), the 920MX is based on Nvidia’s Maxwell architecture. It has 2048 MB of GDDR5 video memory at its disposal.
The various GPU benchmarks show that the 920MX with GDDR5 VRAM is 10 to 30% faster than the DDR3-based models. Therefore, the GPU can trade blows with the DDR3-based variants of the GeForce 930MX.

Gaming Performance
The CPU-GPU combination of the IdeaPad can run many video games smoothly at HD resolution (1366x768) on the low to medium quality settings. Non-demanding titles can be run smoothly at higher resolutions and with better graphical settings. Highly demanding titles like Assassin’s Creed Origins and Kingdom Come: Deliverance are not really playable.
The fast GDDR5 memory makes itself known in a positive fashion. The IdeaPad delivers 10 to 50% higher frame rates than the DDR3-based variants of the 920MX. The DDR3-based variants of the 930MX are frequently beaten as well.

Emissions & Energy Management
System Noise
No matter the load, the IdeaPad does not produce too much noise. When idle, the fan often stands still. It works with a low speed and is practically inaudible. Under load, the fan does not spin very fast. During the stress test, the noise level peaked at 36.2 dB(A). No unusual noises are coming from the notebook.

Temperature
In our stress test (Prime95 and FurMark running for one straight hour), the IdeaPad gets the same results both when running on battery power and when plugged in. The processor runs constantly at 2.5 GHz while the core clock of the GPU fluctuates between 950 and 980 MHz.
The laptop does not get particularly hot. During the stress test, the 40-degree Celsius (104 Fahrenheit) mark is exceeded at a few measurement points.
(-) The maximum temperature on the upper side is 45.2 °C / 113 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(±) The bottom heats up to a maximum of 40 °C / 104 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 25.8 °C / 78 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 28 °C / 82.4 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-0.3 °C / -0.5 F).

Battery Life
Our practically oriented Wi-Fi test simulates loads that are consistent with surfing the web. The “balanced” power plan is selected, the display brightness set to 150 cd/m² and the energy-saving functions are turned off. The IdeaPad achieves a battery runtime of eight hours and fifty minutes. Therefore, it lasts seventy minutes longer than the previously reviewed sibling model (7 hours 40 minutes). However, it should be noted that our current review device has a battery with a much larger capacity (52.5 Wh) than its sibling model (30 Wh).
Pros
Cons
Verdict
The IdeaPad 320s-14IKB represents a chic, mobile, work-oriented device in the 14-inch form factor. The Core i5 processor offers more than enough performance for such usage scenarios as office work and Internet browsing. The dedicated graphics card allows users to play video games, albeit to a limited extent.
The Lenovo IdeaPad can be portrayed, by and large, as a success. A brighter display and a keyboard backlight would have been a nice touch.
An SSD creates a very responsive system. The replacement of the SSD is possible. For this, you will have to open up the device, though. In addition to the 2.5-inch SSD slot, there is an empty M.2-2280 slot inside the device. Therefore, two SDDs can be put inside the device. Alternatively, you can go for an SSD/HDD combination.
The built-in keyboard has left a good impression, and it is quite suitable for people who have to type a lot. However, it lacks a backlight. The good battery runtimes impress. The IPS screen delights users with great viewing angles and good contrast. However, the display brightness is too low.
Some criticism arises from the fact that the laptop comes with only one RAM slot. Lenovo forgoes the opportunity to enable dual-channel mode and, therefore, leaves some performance on the table.
